UNFCCC Climate Week 1
Yeosu (Republic of Korea)
Tuesday 21st April 2026 - Saturday 25th April 2026
Yeosu (Republic of Korea)
Building on the strong foundation laid in 2025 and past years, the 2026 Climate Weeks will continue to focus on accelerating the operationalization of decisions under the intergovernmental process into action on the ground and building momentum toward COP by facilitating targeted inputs to upcoming meetings.
In the format launched in 2025, the Climate Weeks bring together representatives of Parties and non-Party stakeholders in a global space that will combine several planned UNFCCC mandated meetings, as well as policy and high-impact dialogues, offering a unique opportunity to link the intergovernmental process and the discussions that will feed into COP with the real needs of implementation, while enabling the consolidation of activities to increase efficiency and impact.
The Climate Weeks are held twice a year in different regions, maintaining a global focus in scope and participation. Climate weeks provide a structured yet flexible space for dialogue, capacity-building, and showcasing innovative solutions to support the intergovernmental process and urgent, inclusive, and coordinated climate action.

International Mother Earth Day
--
Wednesday 22nd April 2026
-
The General Assembly designated 22 April as International Mother Earth Day through a resolution adopted in 2009.
The original roots go back to the 1970s when environmental protection was not yet a priority of the national political agendas.
The UN Conference on the Human Environment 1972 in Stockholm marked the beginning of a global awareness of the interdependence between people, other living species and our planet, as well as the establishment of World Environment Day on 5 June and the UN Environment Programme.

World Tuna Day
--
Saturday 2nd May 2026
-
As a result of the amazing qualities of tuna, the fish are threatened by overwhelming demand. According to the latest data, among the seven principal tuna species, 33.3 percent of the stocks are estimated to be fished at biologically unsustainable levels
That is why in December 2016, the United Nations General Assembly voted to officially observe World Tuna Day.
The move underlines the importance of conservation management to ensure that we have systems in place to prevent tuna stocks from crashing. Many countries depend heavily on tuna resources for food security and nutrition, economic development, employment, government revenue, livelihoods, culture, and recreation.

This year’s World Migratory Bird Day (WMBD) campaign will highlight the need for a healthy coexistence between humans and birds. It will focus on creating and adapting environments that support migratory bird populations across all communities, from bustling cities to smaller towns and communities. There are actions everyone can take to protect our shared spaces with wildlife.
In 2025, WMBD will raise awareness about the many challenges migratory birds face due to human activities and expanding urban development. The campaign will advocate for strategic urban planning and conservation efforts that incorporate bird-friendly practices, making sure that our communities become havens for these remarkable travelers. The 2025 theme encourages action from all sectors, including national and local governments, businesses, community groups, and individuals worldwide.

Argus Europe Carbon Conference
Nice (France)
Monday 11th May 2026 - Wednesday 13th May 2026
Nice (France)
The Argus Europe Carbon Conference, a leading forum for carbon market stakeholders, will take place in Nice, France on 11–13 May 2026.
As the EU accelerates toward its 2030 climate targets, reforms across the EU ETS, CBAM, and the developing EU Carbon Removal Framework (CRCF) are reshaping compliance obligations and redefining the cost of decarbonisation for industries operating both within Europe and across global supply chains.
Developments in the voluntary carbon market and the progression of Article 6.4 toward operationalisation remain central as hard-to-abate sector companies are on their pathways towards decarbonisation, with aviation facing new cost signals under CORSIA, and industries such as steel, cement, chemicals, and shipping adapting to tightening compliance obligations and rising carbon cost exposure.
Hosted in one of the key hubs for international climate dialogue and European policy engagement in Nice, France, join the event alongside more than 200 senior-level participants for two days of high-level networking and practical insight across the carbon value chain.

World Bee Day
--
Wednesday 20th May 2026
-
Bees and other pollinators, such as butterflies, bats and hummingbirds, are increasingly under threat from human activities.
Pollination is, however, a fundamental process for the survival of our ecosystems. Nearly 90% of the world’s wild flowering plant species depend, entirely, or at least in part, on animal pollination, along with more than 75% of the world’s food crops and 35% of global agricultural land. Not only do pollinators contribute directly to food security, but they are key to conserving biodiversity.
To raise awareness of the importance of pollinators, the threats they face and their contribution to sustainable development, the UN designated 20 May as World Bee Day.
The goal is to strengthen measures aimed at protecting bees and other pollinators, which would significantly contribute to solving problems related to the global food supply and eliminate hunger in developing countries.
We all depend on pollinators and it is, therefore, crucial to monitor their decline and halt the loss of biodiversity.

To halt or reverse this decline it is vital to transform people’s roles, actions and relationships with biodiversity. Many solutions exist: UNESCO’s diverse networks, programmes and partners have observed positive and inspiring seeds of change around the world. UNESCO also accompanies Member States and their people in their efforts to halt biodiversity loss by understanding, appreciating, safeguarding and using biodiversity sustainably.
Now is time to act for biodiversity! The United Nations has proclaimed May 22 The International Day for Biological Diversity to increase understanding and awareness of biodiversity issues.

International Day for the Fight against Illegal, Unreported and Unregulated Fishing
--
Friday 5th June 2026
-
Fisheries provide a vital source of food, employment, recreation, trade and economic well-being for people throughout the world. In a world of growing population and persistent hunger, fish has emerged as an important commodity for the achievement of food security. However, efforts by the international community to ensure the sustainability of fisheries are being seriously compromised by illegal, unreported and unregulated fishing activities.
According to the UN Food and Agriculture Organization (FAO) illegal, unreported and unregulated fishing activities are responsible for the loss of 11–26 million tonnes of fish each year, which is estimated to have an economic value of US$10–23 billion. To curtail this impact, Target 4 of Goal 14 of the Sustainable Development Agenda adopted in 2015 by the UN General Assembly, specifically urges the international community to “effectively regulate harvesting and end overfishing, illegal, unreported and unregulated fishing and destructive fishing practices”.
World Environment Day
Friday 5th June 2026

The Republic of Korea will host World Environment Day 2025 with a focus on ending plastic pollution globally.
World Environment Day, marked annually on 5 June, was established by the United Nations General Assembly in 1972. Over the past five decades, the Day has grown to be one of the largest global platforms for environmental outreach. Tens of millions of people participate online and through in-person activities, events and actions around the world.
The world produces more than 430 million tonnes of plastic annually, two-thirds of which are short-lived products that soon become waste, filling the ocean and, often, working their way into the human food chain.

Financial Times, FT’s Moral Money and Climate Capital
Financial Time’s Climate & Impact Summit
London (UK)
Wednesday 17th June 2026 - Thursday 18th June 2026
London (UK)
Climate change is reshaping the world in irreversible ways. From extreme weather to biodiversity collapse and water scarcity, the systems that sustain life are under growing strain. Global food supplies are destabilising. Key carbon sinks — forests, wetlands, and permafrost — are, in some instances, turning into carbon sources. The Arctic Ocean is on track for its first ice-free day before 2030.
To meet the Paris Agreement, emissions must fall 43% by 2030. Yet this transformation must take place in economies still largely reliant on fossil fuels, at a time when global electricity demand is projected to double by 2050. There is momentum: in 2024, clean electricity exceeded 40% of global generation, driven by solar, now the world’s cheapest energy source, and clean energy investment also passed $2tn for the first time.
But climate action today means more than cutting emissions. In an era of fragile institutions and geopolitical upheaval, business has a role to play in upholding the principles — accountability, transparency, rule of law — that underpin both climate and economic resilience. This year, the FT’s Climate & Impact Summit brings together the FT’s Moral Money and Climate Capital to host practical discussions on the scale of the crises we face — and the opportunity we still have to shape a fairer and more sustainable society.
World Day to Combat Desertification and Drought
Wednesday 17th June 2026
-
Desertification, land degradation, and drought are among the most pressing environmental challenges of our time, with up to 40% of all land area worldwide already considered degraded.
Healthy land not only provides us with almost 95% of our food but so much more: it clothes and shelters us, provides jobs and livelihoods, and protects us from the worsening droughts, floods and wildfires.
At the same time, growing populations coupled with unsustainable production and consumption patterns fuel demand for natural resources, putting excessive pressure on land to the point of degradation. Desertification and drought are driving forced migration, putting tens of millions of people each year at risk of displacement.
Of the world’s 8 billion inhabitants, over one billion of young people under the age of 25 years live in developing countries, particularly in regions directly dependent on land and natural resources for sustenance. Creating job prospects for rural populations is a viable solution that gives young people access to eco-entrepreneurship opportunities and at the same time to scale up best practices.
This year, the theme of the Desertification and Drought Day “United for Land. Our Legacy. Our Future” spotlights the future of land stewardship — our most precious resource to ensure the stability and prosperity of billions of people around the world.

London Climate Resilience Finance Summit
The Brewery, London (UK)
Thursday 25th June 2026
London (UK)
A one-day summit uniting leaders from the resilience and finance worlds to unlock climate finance — from local communities to the global stage:
Collaborating across the resilience and finance ecosystems to break down silos and unlock climate finance, and strengthen the conditions needed to channel investment from local to global levels
Mobilising public and private capital through global partnerships that focus on removing systemic barriers, creating the right incentives, and directing investment to the communities most at risk
Innovating with expert insights that put real-world solutions front and centre, highlighting scalable models to tackle climate risk, debt, and evolving insurance challenges
Climate impacts are accelerating, yet finance for resilience still falls far short of what is needed. At the same time, governments, regulators, investors and insurers are increasingly recognising that climate risk is financial risk – creating the opportunity to embed resilience into financial decision-making and unlock new investment.
This makes the coming year a critical moment to move from commitments to action and scale the finance needed to protect economies, communities and infrastructure from growing climate threats.
The summit will be hosted at The Brewery, a prestigious central London venue in the heart of the city. Building on the success of 2025, it will bring together senior leaders from government, business, investment and many more, with more than 700 people expected to attend.

International Day for the Conservation of the Mangrove Ecosystem
--
Sunday 26th July 2026
-
The International Day for the Conservation of the Mangrove Ecosystem, adopted by the General Conference of UNESCO in 2015 and celebrated each year on 26 July, aims to raise awareness of the importance of mangrove ecosystems as “a unique, special and vulnerable ecosystem” and to promote solutions for their sustainable management, conservation and uses.
Mangroves are rare, spectacular and prolific ecosystems on the boundary between land and sea. These extra ordinary ecosystems contribute to the wellbeing, food security, and protection of coastal communities worldwide. They support a rich biodiversity and provide a valuable nursery habitat for fish and crustaceans. Mangroves also act as a form of natural coastal defense against storm surges, tsunamis, rising sea levels and erosion. Their soils are highly effective carbon sinks, sequestering vast amounts of carbon.
Yet mangroves are disappearing three to five times faster than overall global forest losses, with serious ecological and socio-economic impacts. Current estimates indicate that mangrove coverage has been divided by two in the past 40 years.

International Day of the World’s Indigenous Peoples
--
Sunday 9th August 2026

In order to raise awareness of the needs of these population groups, every 9 August commemorates the International Day of the World’s Indigenous Peoples. This date, adopted in December 1994 by UN General Assembly resolution 49/214, marks the date of the first meeting of the UN Working Group on Indigenous Populations of the Sub-Commission on the Promotion and Protection of Human Rights held in Geneva in 1982.
Violations of the rights of the world’s Indigenous Peoples have become a persistent problem, sometimes because of a historical burden from their colonization backgrounds and others because of the contrast with a constantly changing society. In response to this problem, let’s remember every August 9 that Indigenous Peoples have the right to make their own decisions and carry them out meaningfully and culturally appropriate to them.

International Day of Clean Air for Blue Skies
--
Monday 7th September 2026
-
UN Member States recognize the need to substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination by 2030, as well as to reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management by 2030.
Clean air is important for the health and day-to-day lives of people, while air pollution is the single greatest environmental risk to human health and one of the main avoidable causes of death and disease globally. Air pollution disproportionately affects women, children and older persons, and also has a negative impact on ecosystems.

International Day for the Preservation of the Ozone Layer
--
Wednesday 16th September 2026
-
In 1994, the United Nations General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer (resolution 49/114).
The principal aim of the Montreal Protocol is to protect the ozone layer by taking measures to control total global production and consumption of substances that deplete it, with the ultimate objective of their elimination on the basis of developments in scientific knowledge and technological information. It is structured around several groups of ozone-depleting substances. The groups of chemicals are classified according to the chemical family and are listed in annexes to the Montreal Protocol text. The Protocol requires the control of nearly 100 chemicals, in several categories. For each group or annex of chemicals, the Treaty sets out a timetable for the phase-out of production and consumption of those substances, with the aim of eventually eliminating them completely.

International Day of Awareness of Food Loss and Waste
--
Tuesday 29th September 2026
-
Food loss and waste undermine the sustainability of our food systems. When food is lost or wasted, all the resources that were used to produce this food – including water, land, energy, labour and capital – go to waste. In addition, the disposal of food loss and waste in landfills, leads to greenhouse gas emissions, contributing to climate change. Food loss and waste can also negatively impact food security and food availability, and contribute to increasing the cost of food.
Our food systems cannot be resilient if they are not sustainable, hence the need to focus on the adoption of integrated approaches designed to reduce food loss and waste. Actions are required globally and locally to maximise the use of the food we produce. The introduction of technologies, innovative solutions (including e-commerce platforms for marketing, retractable mobile food processing systems), new ways of working and good practices to manage food quality and reduce food loss and waste are key to implementing this transformative change.

One of the ways the organization works towards achieving these goals is by calling on citizens from around the globe to collaborate on a range of issues related to poverty reduction, international economic development and finance, building human capital, and strengthening resilience. The primary opportunity to bolster awareness and participation on these topics and advance the agenda on key issues is through the Spring and Annual Meetings. The meetings also aim to open up the meetings to the public through live-streamed events and online conversations on World Bank Live, Twitter and other platforms.

International Day for Preventing the Exploitation of the Environment in War and Armed Conflict
--
Friday 6th November 2026
-
The United Nations Environment Programme (UNEP) has found that over the last 60 years, at least 40 percent of all internal conflicts have been linked to the exploitation of natural resources, whether high-value resources such as timber, diamonds, gold and oil, or scarce resources such as fertile land and water. Conflicts involving natural resources have also been found to be twice as likely to relapse.
The United Nations attaches great importance to ensuring that action on the environment is part of conflict prevention, peacekeeping and peacebuilding strategies, because there can be no durable peace if the natural resources that sustain livelihoods and ecosystems are destroyed.
On 5 November 2001, the UN General Assembly declared 6 November of each year as the International Day for Preventing the Exploitation of the Environment in War and Armed Conflict (A/RES/56/4).

World Soil Day

Saturday 5th December 2026

World Soil Day (WSD) is held annually on 5 December as a means to focus attention on the importance of healthy soil and to advocate for the sustainable management of soil resources.
An international day to celebrate soil was recommended by the International Union of Soil Sciences (IUSS) in 2002. Under the leadership of the Kingdom of Thailand and within the framework of the Global Soil Partnership, FAO has supported the formal establishment of WSD as a global awareness raising platform. The FAO Conference unanimously endorsed World Soil Day in June 2013 and requested its official adoption at the 68th UN General Assembly. In December 2013, the UN General Assembly responded by designating 5 December 2014 as the first official World Soil Day.

Human Rights Day is observed every year on 10 December – the day on which the United Nations General Assembly adopted, in 1948, the Universal Declaration of Human Rights.
The Universal Declaration of Human Rights empowers us all. The principles enshrined in the Declaration are as relevant today as they were in 1948. We need to stand up for our own rights and those of others. We can take action in our own daily lives, to uphold the rights that protect us all and thereby promote the kinship of all human beings.

Yeosu (Republic of Korea)
Tuesday 21st April 2026 - Saturday 25th April 2026
Yeosu (Republic of Korea)
Building on the strong foundation laid in 2025 and past years, the 2026 Climate Weeks will continue to focus on accelerating the operationalization of decisions under the intergovernmental process into action on the ground and building momentum toward COP by facilitating targeted inputs to upcoming meetings.
In the format launched in 2025, the Climate Weeks bring together representatives of Parties and non-Party stakeholders in a global space that will combine several planned UNFCCC mandated meetings, as well as policy and high-impact dialogues, offering a unique opportunity to link the intergovernmental process and the discussions that will feed into COP with the real needs of implementation, while enabling the consolidation of activities to increase efficiency and impact.
The Climate Weeks are held twice a year in different regions, maintaining a global focus in scope and participation. Climate weeks provide a structured yet flexible space for dialogue, capacity-building, and showcasing innovative solutions to support the intergovernmental process and urgent, inclusive, and coordinated climate action.
International Mother Earth Day
--
Wednesday 22nd April 2026
-
The General Assembly designated 22 April as International Mother Earth Day through a resolution adopted in 2009.
The original roots go back to the 1970s when environmental protection was not yet a priority of the national political agendas.
The UN Conference on the Human Environment 1972 in Stockholm marked the beginning of a global awareness of the interdependence between people, other living species and our planet, as well as the establishment of World Environment Day on 5 June and the UN Environment Programme.
World Tuna Day
--
Saturday 2nd May 2026
-
As a result of the amazing qualities of tuna, the fish are threatened by overwhelming demand. According to the latest data, among the seven principal tuna species, 33.3 percent of the stocks are estimated to be fished at biologically unsustainable levels
That is why in December 2016, the United Nations General Assembly voted to officially observe World Tuna Day.
The move underlines the importance of conservation management to ensure that we have systems in place to prevent tuna stocks from crashing. Many countries depend heavily on tuna resources for food security and nutrition, economic development, employment, government revenue, livelihoods, culture, and recreation.

Argus Europe Carbon Conference
Nice (France)
Monday 11th May 2026 - Wednesday 13th May 2026
Nice (France)
The Argus Europe Carbon Conference, a leading forum for carbon market stakeholders, will take place in Nice, France on 11–13 May 2026.
As the EU accelerates toward its 2030 climate targets, reforms across the EU ETS, CBAM, and the developing EU Carbon Removal Framework (CRCF) are reshaping compliance obligations and redefining the cost of decarbonisation for industries operating both within Europe and across global supply chains.
Developments in the voluntary carbon market and the progression of Article 6.4 toward operationalisation remain central as hard-to-abate sector companies are on their pathways towards decarbonisation, with aviation facing new cost signals under CORSIA, and industries such as steel, cement, chemicals, and shipping adapting to tightening compliance obligations and rising carbon cost exposure.
Hosted in one of the key hubs for international climate dialogue and European policy engagement in Nice, France, join the event alongside more than 200 senior-level participants for two days of high-level networking and practical insight across the carbon value chain.

World Bee Day
--
Wednesday 20th May 2026
-
Bees and other pollinators, such as butterflies, bats and hummingbirds, are increasingly under threat from human activities.
Pollination is, however, a fundamental process for the survival of our ecosystems. Nearly 90% of the world’s wild flowering plant species depend, entirely, or at least in part, on animal pollination, along with more than 75% of the world’s food crops and 35% of global agricultural land. Not only do pollinators contribute directly to food security, but they are key to conserving biodiversity.
To raise awareness of the importance of pollinators, the threats they face and their contribution to sustainable development, the UN designated 20 May as World Bee Day.
The goal is to strengthen measures aimed at protecting bees and other pollinators, which would significantly contribute to solving problems related to the global food supply and eliminate hunger in developing countries.
We all depend on pollinators and it is, therefore, crucial to monitor their decline and halt the loss of biodiversity.
International Day for Biological Diversity

International Day for the Fight against Illegal, Unreported and Unregulated Fishing
--
Friday 5th June 2026
-
Fisheries provide a vital source of food, employment, recreation, trade and economic well-being for people throughout the world. In a world of growing population and persistent hunger, fish has emerged as an important commodity for the achievement of food security. However, efforts by the international community to ensure the sustainability of fisheries are being seriously compromised by illegal, unreported and unregulated fishing activities.
According to the UN Food and Agriculture Organization (FAO) illegal, unreported and unregulated fishing activities are responsible for the loss of 11–26 million tonnes of fish each year, which is estimated to have an economic value of US$10–23 billion. To curtail this impact, Target 4 of Goal 14 of the Sustainable Development Agenda adopted in 2015 by the UN General Assembly, specifically urges the international community to “effectively regulate harvesting and end overfishing, illegal, unreported and unregulated fishing and destructive fishing practices”.

Financial Times, FT’s Moral Money and Climate Capital
Financial Time’s Climate & Impact Summit
London (UK)
Wednesday 17th June 2026 - Thursday 18th June 2026
London (UK)
Climate change is reshaping the world in irreversible ways. From extreme weather to biodiversity collapse and water scarcity, the systems that sustain life are under growing strain. Global food supplies are destabilising. Key carbon sinks — forests, wetlands, and permafrost — are, in some instances, turning into carbon sources. The Arctic Ocean is on track for its first ice-free day before 2030.
To meet the Paris Agreement, emissions must fall 43% by 2030. Yet this transformation must take place in economies still largely reliant on fossil fuels, at a time when global electricity demand is projected to double by 2050. There is momentum: in 2024, clean electricity exceeded 40% of global generation, driven by solar, now the world’s cheapest energy source, and clean energy investment also passed $2tn for the first time.
But climate action today means more than cutting emissions. In an era of fragile institutions and geopolitical upheaval, business has a role to play in upholding the principles — accountability, transparency, rule of law — that underpin both climate and economic resilience. This year, the FT’s Climate & Impact Summit brings together the FT’s Moral Money and Climate Capital to host practical discussions on the scale of the crises we face — and the opportunity we still have to shape a fairer and more sustainable society.
World Day to Combat Desertification and Drought
Wednesday 17th June 2026
-
Desertification, land degradation, and drought are among the most pressing environmental challenges of our time, with up to 40% of all land area worldwide already considered degraded.
Healthy land not only provides us with almost 95% of our food but so much more: it clothes and shelters us, provides jobs and livelihoods, and protects us from the worsening droughts, floods and wildfires.
At the same time, growing populations coupled with unsustainable production and consumption patterns fuel demand for natural resources, putting excessive pressure on land to the point of degradation. Desertification and drought are driving forced migration, putting tens of millions of people each year at risk of displacement.
Of the world’s 8 billion inhabitants, over one billion of young people under the age of 25 years live in developing countries, particularly in regions directly dependent on land and natural resources for sustenance. Creating job prospects for rural populations is a viable solution that gives young people access to eco-entrepreneurship opportunities and at the same time to scale up best practices.
This year, the theme of the Desertification and Drought Day “United for Land. Our Legacy. Our Future” spotlights the future of land stewardship — our most precious resource to ensure the stability and prosperity of billions of people around the world.

London Climate Resilience Finance Summit
The Brewery, London (UK)
Thursday 25th June 2026
London (UK)
A one-day summit uniting leaders from the resilience and finance worlds to unlock climate finance — from local communities to the global stage:
Collaborating across the resilience and finance ecosystems to break down silos and unlock climate finance, and strengthen the conditions needed to channel investment from local to global levels
Mobilising public and private capital through global partnerships that focus on removing systemic barriers, creating the right incentives, and directing investment to the communities most at risk
Innovating with expert insights that put real-world solutions front and centre, highlighting scalable models to tackle climate risk, debt, and evolving insurance challenges
Climate impacts are accelerating, yet finance for resilience still falls far short of what is needed. At the same time, governments, regulators, investors and insurers are increasingly recognising that climate risk is financial risk – creating the opportunity to embed resilience into financial decision-making and unlock new investment.
This makes the coming year a critical moment to move from commitments to action and scale the finance needed to protect economies, communities and infrastructure from growing climate threats.
The summit will be hosted at The Brewery, a prestigious central London venue in the heart of the city. Building on the success of 2025, it will bring together senior leaders from government, business, investment and many more, with more than 700 people expected to attend.

International Day for the Conservation of the Mangrove Ecosystem
--
Sunday 26th July 2026
-
The International Day for the Conservation of the Mangrove Ecosystem, adopted by the General Conference of UNESCO in 2015 and celebrated each year on 26 July, aims to raise awareness of the importance of mangrove ecosystems as “a unique, special and vulnerable ecosystem” and to promote solutions for their sustainable management, conservation and uses.
Mangroves are rare, spectacular and prolific ecosystems on the boundary between land and sea. These extra ordinary ecosystems contribute to the wellbeing, food security, and protection of coastal communities worldwide. They support a rich biodiversity and provide a valuable nursery habitat for fish and crustaceans. Mangroves also act as a form of natural coastal defense against storm surges, tsunamis, rising sea levels and erosion. Their soils are highly effective carbon sinks, sequestering vast amounts of carbon.
Yet mangroves are disappearing three to five times faster than overall global forest losses, with serious ecological and socio-economic impacts. Current estimates indicate that mangrove coverage has been divided by two in the past 40 years.

International Day of the World’s Indigenous Peoples
--
Sunday 9th August 2026
-
In order to raise awareness of the needs of these population groups, every 9 August commemorates the International Day of the World’s Indigenous Peoples. This date, adopted in December 1994 by UN General Assembly resolution 49/214, marks the date of the first meeting of the UN Working Group on Indigenous Populations of the Sub-Commission on the Promotion and Protection of Human Rights held in Geneva in 1982.
Violations of the rights of the world’s Indigenous Peoples have become a persistent problem, sometimes because of a historical burden from their colonization backgrounds and others because of the contrast with a constantly changing society. In response to this problem, let’s remember every August 9 that Indigenous Peoples have the right to make their own decisions and carry them out meaningfully and culturally appropriate to them.

International Day of Clean Air for Blue Skies
--
Monday 7th September 2026
-
UN Member States recognize the need to substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination by 2030, as well as to reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management by 2030.
Clean air is important for the health and day-to-day lives of people, while air pollution is the single greatest environmental risk to human health and one of the main avoidable causes of death and disease globally. Air pollution disproportionately affects women, children and older persons, and also has a negative impact on ecosystems.
International Day for the Preservation of the Ozone Layer

In 1994, the United Nations General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer (resolution 49/114).
The principal aim of the Montreal Protocol is to protect the ozone layer by taking measures to control total global production and consumption of substances that deplete it, with the ultimate objective of their elimination on the basis of developments in scientific knowledge and technological information. It is structured around several groups of ozone-depleting substances. The groups of chemicals are classified according to the chemical family and are listed in annexes to the Montreal Protocol text. The Protocol requires the control of nearly 100 chemicals, in several categories. For each group or annex of chemicals, the Treaty sets out a timetable for the phase-out of production and consumption of those substances, with the aim of eventually eliminating them completely.

International Day of Awareness of Food Loss and Waste
--
Tuesday 29th September 2026
-
Food loss and waste undermine the sustainability of our food systems. When food is lost or wasted, all the resources that were used to produce this food – including water, land, energy, labour and capital – go to waste. In addition, the disposal of food loss and waste in landfills, leads to greenhouse gas emissions, contributing to climate change. Food loss and waste can also negatively impact food security and food availability, and contribute to increasing the cost of food.
Our food systems cannot be resilient if they are not sustainable, hence the need to focus on the adoption of integrated approaches designed to reduce food loss and waste. Actions are required globally and locally to maximise the use of the food we produce. The introduction of technologies, innovative solutions (including e-commerce platforms for marketing, retractable mobile food processing systems), new ways of working and good practices to manage food quality and reduce food loss and waste are key to implementing this transformative change.

The World Bank Group (WBG) plays a key role in the global effort to end extreme poverty and boost shared prosperity. One of the ways the organization works towards achieving these goals is by calling on citizens from around the globe to collaborate on a range of issues related to poverty reduction, international economic development and finance, building human capital, and strengthening resilience. The primary opportunity to bolster awareness and participation on these topics and advance the agenda on key issues is through the Spring and Annual Meetings. The meetings also aim to open up the meetings to the public through live-streamed events and online conversations on World Bank Live, Twitter and other platforms.

International Day for Preventing the Exploitation of the Environment in War and Armed Conflict

Friday 6th November 2026

The United Nations Environment Programme (UNEP) has found that over the last 60 years, at least 40 percent of all internal conflicts have been linked to the exploitation of natural resources, whether high-value resources such as timber, diamonds, gold and oil, or scarce resources such as fertile land and water. Conflicts involving natural resources have also been found to be twice as likely to relapse.
The United Nations attaches great importance to ensuring that action on the environment is part of conflict prevention, peacekeeping and peacebuilding strategies, because there can be no durable peace if the natural resources that sustain livelihoods and ecosystems are destroyed.
On 5 November 2001, the UN General Assembly declared 6 November of each year as the International Day for Preventing the Exploitation of the Environment in War and Armed Conflict (A/RES/56/4).

An international day to celebrate soil was recommended by the International Union of Soil Sciences (IUSS) in 2002. Under the leadership of the Kingdom of Thailand and within the framework of the Global Soil Partnership, FAO has supported the formal establishment of WSD as a global awareness raising platform. The FAO Conference unanimously endorsed World Soil Day in June 2013 and requested its official adoption at the 68th UN General Assembly. In December 2013, the UN General Assembly responded by designating 5 December 2014 as the first official World Soil Day.
